Complete written investigation summary
In October 2019, a crew impersonating DEA agents kidnapped a Naperville businessman from a parking lot in front of security cameras — then spent the night torturing him while demanding a $500,000 ransom. The man who organized it, Sedgwick Williams, had done something almost identical fifteen years before. He had been convicted. Then the conviction was reversed, and he walked free.

Sedgwick Williams is the Chicago man convicted of organizing a crew that impersonated DEA agents and police officers to commit kidnappings and armed robberies across Chicago and its suburbs in 2019. He was found guilty on all eight counts he faced at trial and sentenced to 600 months (50 years) in federal prison by U.S. District Judge Jorge Alonso on May 7, 2025.
In fall 2019, the crew robbed a high-stakes poker game while posing as law enforcement, then abducted and tortured a Naperville businessman for hours while demanding a $500,000 ransom, forced a Westchester family into their own basement at gunpoint, attempted to abduct a man on Interstate 88, and tried to enter a home in South Holland. They used DEA-stamped ballistic vests, badges, handcuffs, and a vehicle rigged with working emergency lights and a siren.
The operation ended on December 11 to 12, 2019, when a man in South Holland refused to open his door to men posing as police and called 911 instead. South Holland officers arrived and two crew members, Tai Hon La and Ivan Ayers, were arrested. Sedgwick Williams was stopped in a vehicle a block away. Investigators recovered two guns, two ballistic vests, handcuffs, and a police scanner.
Yes. According to a published Illinois Appellate Court opinion, Williams was charged with aggravated kidnapping in a 2004 case involving a family taken to a basement, convicted, and sentenced to 25 years. In 2008, the Illinois Appellate Court reversed that conviction, finding the child witness identifications unreliable. He was released on August 5, 2008. In 2019 he was on probation for identity deception when he organized the fake-DEA crew.
The federal case is United States v. Sedgwick Williams et al., Case No. 1:19-cr-00932, in the U.S. District Court for the Northern District of Illinois, Eastern Division, before Judge Jorge Alonso.
Yes. DNA recovered from the car used in the Naperville kidnapping matched three individuals in the national CODIS database who were never identified. The trial judge ruled this evidence could not be shown to the jury. The FBI also stated there may be additional victims who never came forward because they believed they had been robbed by real federal agents.
